Scientists Invent 30 Year Continuous Power Laptop Battery

Scientists Invent 30 Year Continuous Power Laptop Battery Your next laptop could have a continuous power battery that lasts for 30 years without a single recharge thanks to work being funded by the U.S. Air Force Research Laboratory. The breakthrough betavoltaic power cells are constructed from semiconductors and use radioisotopes as the energy source. As the radioactive material decays it emits beta particles that transform into electric power capable of fueling an electrical device like a laptop for years.
Although betavoltaic batteries sound Nuclear they’re not, they’re neither use fission/fusion or chemical processes to produce energy and so (do not produce any radioactive or hazardous waste). Betavoltaics generate power when an electron strikes a particular interface between two layers of material. The Process uses beta electron emissions that occur when a neutron decays into a proton which causes a forward bias in the semiconductor. This makes the betavoltaic cell a forward bias diode of sorts, similar in some respects to a photovoltaic (solar) cell. Electrons scatter out of their normal orbits in the semiconductor and into the circuit creating a usable electric current.
The profile of the batteries can be quite small and thin, a porous silicon material is used to collect the hydrogen isotope tritium which is generated in the process. The reaction is non-thermal which means laptops and other small devices like mobile phones will run much cooler than with traditional lithium-ion power batteries. The reason the battery lasts so long is that neutron beta-decay into protons is the world's most concentrated source of electricity, truly demonstrating Einstein’s theory E=MC2.
The best part about these cells are when they eventually run out of power they are totally inert and non-toxic, so environmentalists need not fear these high tech scientific wonder batteries. If all goes well plans are for these cells to reach store shelves in about 2 to 3 years.

That's fantastic. Or a mobile phone that never dies!

[marcode]

sounds a bit too good to be true.

so you mean samsung phones wont have them

[B.I.G.]

Imagine how much it would cost.

One that lasted a 24 hours would do me instead of the pointless few hours which is what i get out of my laptop battery at present.

I'd imagine that people would pay a hundred quid of so for a mobile phone bat that never ran out! Will be interesting to see pricing on them though, sounds bloody expensive mind

Dont like the sound of that sitting on my lap close to my balls.

[gatch.]

a mobile phone that never dies!!!! then what excuse would you use on the missus when you don't answer her calls???? sounds terrible to me although the laptop side of it sounds great!

[TwoPlAnKs]

when does any portable electric device last 30 years though? you'd end up buying a new phone or laptop and taking the battery out of the old one

gonna fairly fuck up the battery economy too, unless these things are incredibly expensive

crappy battery life is one of the main reasons i've not got a laptop though so bring it on

If they could get this to work on cars and all household appliances then Iran could be nuked .

I remember hearing about a battery that can be charged up in a matter of seconds (possibly on this forum) and that was a few years ago i believe. Still no sign of those. I'll believe these when I see em..
